FIELD OF THE INVENTION

The present invention relates to a charging device, and moreparticularly to a charging device applied to a transmitter. Thetransmitter is a reusable electronic device for collecting physiologicalsignals of the living body and transmitting them out in a continuousphysiological signal measuring device, and the charging device is usedto charge the transmitter.

BACKGROUND OF THE INVENTION

With the recent advancements of current technology and changinglifestyles, some tests which had to be tested in the hospital in thepast have now changed to home measurement. In particular, the change inlifestyles has led to an increase in patients with chronic diseases,which has accelerated the development of this industry. The measurementof blood glucose is a testing item, and the measurement of blood glucoseconcentration in the blood is an important step for effectivelymonitoring and treating diabetes. For the past two decades, thecontinuous glucose monitoring (CGM) system has developed rapidly. Inaddition, because the CGM system must be worn by the user for a longtime, the miniaturization of the device has become an inevitable trend.Generally, the basic structure of the CGM system mostly includes asensor, a transmitter and a sensor inserter. The sensor is used tomeasure the physiological signal corresponding to the glucoseconcentration in the human body. The transmitter is usually assembledwith a patch base with a transmitter installed to receive and transmitthe physiological signal. The sensor inserter is usually a mechanicaldevice for attaching the patch base with the sensor installed to theskin surface of the living body, and enabling a part of the transmitterto be implanted under the skin of the user. The transmitter is arelatively expensive electronic element and usually contains theprocessing element for processing the signal from the transmitter andtransmitting the processed signal in a wireless way. Therefore, ideallyif the transmitter is a reusable element, the purposes of environmentalprotection and cost reduction can be achieved. Hence, in order to allowthe transmitter to be reused, it is necessary to supplement the powerfor the transmitter. In order to avoid the pollution of the wastebattery which may be caused by using the ordinary battery, the batteryin the transmitter is mostly a rechargeable battery. Thus, in thistechnical field, a charger used in conjunction with the transmitter isrequired.

In order to overcome the drawbacks in the prior art, a charging devicefor a physiological signal transmitter and a charging method for thesame is disclosed. The particular design in the present invention notonly solves the problems described above, but also it is easy toimplement. Thus, the present invention has utility for the industry.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will now be described more specifically withreference to the following embodiments. It is to be noted that thefollowing descriptions of preferred embodiments of this invention arepresented herein for the purposes of illustration and description only;they are not intended to be exhaustive or to be limited to the preciseform disclosed.

Please refer to FIGS. 1A-1G. FIGS. 1A-1D are presented at differentangles to fully show the relative positions and connecting relationshipsamong elements and structures. As shown in FIGS. 1A-1D, a chargingdevice 1 has a main body 10, usually a shell-shaped object, fordisposing and protecting the required elements and structures therein.The charging device 1 also has a placing portion 13 having a bearingsurface 13′ for placing the physiological signal transmitter 7(hereinafter referred to as the transmitter 7). The placing portion 13is similar to a slot or a pocket-like structure, and formed by a coverplate 10 a 1 with the bearing surface 13′ for the transmitter 7 to belaterally inserted thereinto. In other embodiments, the placing portion13 is also not limited to other configurations. In FIG. 1B, when thetransmitter 7 is correctly placed in the placing portion 13, a baffle 61protrudes from a baffle outlet 16 to position the transmitter 7 in theplacing portion 13 to prevent the transmitter 7 from leaving the placingportion 13. At the same time, a plug 44 (or referred to as a thirdelectrical connecting port) also protrudes out of the body 10. FIGS. 1Aand 1D disclose that there is an opening 15 (or referred to as a liftingchannel) in the placing portion 13 for a charging seat 30 of a secondelectrical connecting port 3′ to lift therein; that is, a placingportion 13 is formed on the outside or top of the second electricalconnecting port 3′ or the charging pedestal 30. In addition, in order toavoid the abnormal movement of the charging seat 30, a guiding portion150 is further disposed in the opening 15 (please see FIG. 5E) toprevent the charging seat 30 from shaking on all sides or rotating inthe lifting process, and a sliding groove 150′ is formed between theguiding portion 150. Moreover, a first conductive connector 31, usuallyin the form of a gold finger, is fixed on the charging seat 30 for beingelectrically connecting to the electrical connecting port 73 of thetransmitter 7 of FIG. 3D. Furthermore, FIGS. 1C and 1D disclose that inthe placing portion 13, upper restricting ribs 101 are disposed on theinner surface of the cover plate 10 a 1, and side restricting ribs 102are disposed on the inner surfaces of the two side walls of the coverplate 10 a 1 to reduce the contact area between the charging device 1and the transmitter 7 so as to reduce the frictional force when placingor removing the transmitter 7 in the charging device 1. Moreover, therestricting ribs 101, 102 also helps the transmitter 7 to be positionedon the charging seat 30, and prevents the transmitter 7 from shaking orbeing difficult to remove. Furthermore, when producing the upper housing10 a, the restricting ribs 101, 102 also help the upper housing 10 a tobe separated from the mold. The cover plate 10 a 1 is used to shield theopening 15, which is beneficial to the electrostatic protection, and canalso prevent improper foreign objects from hitting the first conductiveconnector 31 and/or the charging seat 30. In another embodiment, thecharging device 10 can also omit the cover plate 10 a 1, or canappropriately shield the front, the side, and the top of the transmitter7 without the cover plate 10 a 1. In addition, the push-pull key 12 forcontrolling the operating module 4 (please refer to FIG. 2) protrudesout of the housing 10, and the user controls the action of the operatingmodule 4 via the push-pull key 12.

Please refer to FIG. 1D, which discloses that when the transmitter 7 isnot placed at a predetermined position, e.g. having not been placed orbeing not correctly placed in the placing portion 13, an actuating end51 protrudes into the placing portion 13. The actuating end 51 belongsto a first locking module 5 (also referred to as a stopping module 5).When the transmitter 7 is correctly placed in the placing portion 13,the actuating end 51 is pressed to move downward. The detailed operatingprinciple will be described later (please refer to FIGS. 4C and 6C).

Please refer to FIG. 1E. The push-pull key 12 is disposed at the bottomof the housing 10, and further has a positioning block 120. A firstpositioning groove 103 a and a second positioning groove 103 b arecorrespondingly formed on the housing 10. The positioning block 120 ofFIG. 1E is engaged with the first positioning groove 103 a to maintainthe push-pull key 12 in the first operating state. When the user pressesthe push-pull key 12 toward the inside of the housing 10, thepositioning block 120 can be separated from the first positioninggroove. Then, when the push-pull key 12 is pushed to the secondpositioning groove 103 b, the positioning block 120 can be engaged withthe second positioning groove 103 b (please refer to FIG. 6G). Pleaserefer to FIG. 1F, which discloses a rear (back part) view of thecharging device 1. The restricting ribs 101 are disposed on the innersurfaces of the cover plate 10 a 1. Moreover, it also can be seen that afirst matching portion 14 is protrudingly disposed at the deepest partof the placing portion 13. Please refer to FIG. 1G, which discloses thatthe width W2 of the placing portion 13 of the charging device 1 is lessthan or equal to the width W1 of the transmitter 7. When the user wantsto take out the transmitter 7, he can conveniently hold and clamp thetransmitter 7 from the left and right sides of the placing portion 13without clamping the charging device 1 at the same time.

Please refer to FIG. 2, which is an exploded view according to a firstembodiment of the present invention. It can be seen that the housing(body) 10 in FIGS. 1A-1G can be further divided into an upper housing 10a and a lower housing 10 b. The upper housing 10 a includes theaforementioned indicating area 11, the cover plate 10 a 1, and theplacing portion 13 having a bearing surface 13′ formed thereon, most ofwhich have been described above, and will not be repeated here. A secondmatching portion 70 is formed on the transmitter 7. As described above,it can be seen in FIG. 2 that the shape of the indicating area 11 issimilar to that of the second matching portion 70. This design can beused to visually remind the user of the direction to put the transmitter7 into the charging device. The first matching portion 14 on thecharging device is a convex shape (please refer to FIG. 1F), and thesecond matching portion 70 on the transmitter 7 is a concave shape. Whenthe first matching portion and the second matching portion are combinedwith each other, a foolproof structure is formed, and the firstconnecting port 73 and the opening 15 are correctly aligned (not shown).

Please continue to refer to FIG. 2. The charging device 1 includes acharging module 3. The charging module includes a second electricalconnecting port 3′, a circuit assembly 33, and a third connecting port44. The second connecting port 3′ includes a charging seat 30, and afirst conductive connector 31 and a second conductive connector 32 aredisposed on the charging seat 30. The first conductive connector 31 isusually a golden finger type connector for transmitting the power andthe signal. The second conductive connector 32 is usually a pogo pin forserving as the ground. On the lateral side of the charging seat 30,there is a second guiding structure 301 to serve as a sliding element,and the first sliding element 301 is disposed on the charging seat 30via a sliding element pedestal 302. The circuit assembly 33 is used toperform the charging and the charging control or the signal transmittingcontrol for the physiological signal transmitter. One end of the circuitassembly 33 is a circuit board 330. The circuit board 330 is equippedwith a light-emitting element 332 and other related electronic elements,and electrically connected to the first conductive connector 31 and thesecond conductive connector 32. Above the light-emitting element 332,there is a light-guiding element 52′ disposed in the upper housing 10 a.The light-guiding element 52′ is usually located in the first matchingportion 14 (please see FIG. 1F), and its shape is usually just fit theindicating area 11. Therefore, the indicating area 11 is made of atransparent or translucent material, or itself serves as a part of thelight-guiding element 52′; that is, the shape of the light-guidingelement 52′ is corresponding to the second matching portion 70, and theindicator area 11 also serves as a light signal area. The other end ofthe circuit assembly 33 is a flexible electrical connecting element 331,which is usually a flexible printed circuit for maintaining theelectrical connection with the plug 44 serving as a third electricalconnecting port to input power source. The flexible electricalconnecting element 331 can also be replaced with a sliding pinconductive structure or a sliding rail conductive structure.

Please continue to refer to FIG. 2. The charging device 1 includes anoperating module 4. The operating module 4 includes an operating portion40 for driving the second electrical connecting port 30 to beelectrically connected to the first electrical connecting port 73 of thetransmitter 7. The operating portion 40 has a third electricalconnecting port 44 assembled thereon, and has a first guiding structure41. The first guiding structure 41 is usually a sliding rail or asliding groove for coupling with the first sliding element 301. When theoperating portion 40 is driven to move laterally, the first guidingstructure 41 guides the first sliding element 301 to movelongitudinally, thereby driving the charging seat 30 to move up anddown. Hence, the first sliding element 301 also serves as a secondguiding structure. In addition, the aforementioned push-pull key 12 isdisposed below the operating portion 40; that is, the user drives theoperating portion 40 to move laterally via the push-pull key 12 (for thedetailed operations, please refer to FIGS. 7A and 7B). The push-pull key12 and the operating portion 40 can be integrally formed, or they arerespectively independent elements.

Please continue to refer to FIG. 2. The charging device 1 furtherincludes a first locking module 5 (or referred to as a stopping module 5and a first locking portion 5) for releasably restricting the movementof the second electrical connecting port 3′. One end of the stoppingmodule 5 is an actuating end 51, and the other end thereof is a stoppingend 52. The actuating end 51 extends into the placing portion 13, i.e.protruding from the bearing surface 13′, and the stopping end 52 iscoupled with a blocked portion 43 disposed on the operating portion 40;that is, the blocked portion 43 is blocked by the stopping end 52 sothat it cannot move laterally. Therefore, the operating portion 40cannot guide the first sliding element 301 to move longitudinally viathe first guiding structure 41. Hence, the first locking module 5achieves the effect of indirectly restricting the movement of the secondelectrical connecting port 3′. Moreover, the first locking module 5further includes an elastic element 53 for keeping the actuating end 51normally extending into the placing portion 13 when the transmitter 7 isnot placed in the placing portion 13. At this time, the stopping end 52also keeps normally stopping the blocked portion 43. There is a pivotingportion 50 between the actuating end 51 and the stopping end 52. Thepivoting portion 50 is pivoted to the pivoting frame 10 b 2 of the lowerhousing 10 b. When the actuating end 51 is pressed by the transmitter 7,the first locking module 5 can rotate with the pivoting portion 50 asthe center of rotation, and rotate with the pivoting frame 10 b 2 as thefulcrum (for detailed front and rear operations, please refer to FIGS.4B and 5A).

Please continue to refer to FIG. 2. The charging device 1 furtherincludes a second locking module 6 (or referred to as a second lockingportion 6, a positioning module 6, and a baffle 61). The positioningmodule 6 is disposed on the charging device 1 near the rear side, has abaffle 61 which can extend from the baffle exit 16 to reach the placingportion 13, and has an elastic element 62 for providing the baffle 61with an elastic force to enable the baffle 61 to extend from the baffleoutlet 16. The second locking module 6 also has a first connecting end60 for connecting to the second connecting end 42. The second lockingmodule 6 also has a guiding structure 63, which is a notch, coupled to aguiding element 10 b 1 of the lower housing 10 b so that the baffle 61can only move in the up and down directions without shifting or rotating(for the detailed operations, please refer to FIGS. 4C and 6C). In otherembodiments, a part of the charging module 3, the operating module 4,the first locking module 5, or the second locking module 6 can form ahousing structure similar to the lower housing 10 b to form an internalspace with the upper housing 10 to accommodate various elements (notshown). The operating module 4, the first locking module 5, and thesecond locking module 6 are collectively referred to as a controllingmodule. The controlling module is used to control the operating processbetween the transmitter 7 and the charging module 3 to maintain a safestate so that when the transmitter 7 and the second electricalconnecting ports 3′ are separated or connected, the transmitter 7 canboth be protected. This prevents the parts from being damaged due to theimproper operation by the user (for the detailed operations, pleaserefer to FIGS. 4A to 6C). In other embodiments, the first locking module5 or the second locking module 6 respectively collocates with theoperating module 4, and the first locking module 5, the second lockingmodule 6, and the operating module 4 are collectively referred to as acontrol module.

Please refer to FIGS. 3A to 3D, wherein 3A shows that the transmitter 7is detachably disposed on a sensor module 8 and connected to the sensorassembly 81, and the sensor module 8 includes a sensor pedestal 80 andthe sensor assembly 81. The sensor pedestal 80 can be adhered to theskin S through an adhesive sheet ST, at this time the transmitter 7 isconfigured to transmit the signal from the sensor 810 to the outside.

Please refer to FIGS. 3B to 3D. The transmitter 7 includes a battery 71and a first electrical-connecting port 73 having an input portion 730which has a groove structure used to match the structure of either thesensor assembly 81 or a second electrical-connecting port 30 and aninsert hole 731 equipped with an input terminal 732 and a secondaryinput terminal 733. The battery 71 provides electric power for theoperation such as signal output of the transmitter 7. The input terminal732 is used for electrically connecting the output terminal 812 or thefirst conductive connector 31. In addition, the transmitter 7 alsoincludes a first buckling structure 72 for buckling and fixing with thesecond buckling structure 83 of the sensor pedestal 80. The sensorassembly 81 is fixed in the sensor assembly fixing structure 82 of thesensor base 80. The piercing end 811 of the sensor 810 penetrates thesubcutaneous tissue SC, while the output terminal 812 of the sensor 810enters the input portion 73 and is electrically connected to the inputterminal 730 in the transmitter 7, so the signal measured by the sensor810 can be transmitted to the outside through the transmitter 7. Inorder to prevent the transmitter 7 from being installed on the sensorbase 80 in a wrong direction, the sensor pedestal 80 further includes amatching positioning portion 84 for matching with the second matchingportion 70, so that when a user tends to cover the transmitter 7 on thesensor base 80, the installation direction can be identified through theappearance of the structure to achieve the effect of being foolproof.The transmitter 7 of the present invention is only one embodimentthereof, and the charging device 1 of the present invention can also beapplied to other types of transmitters. The physiological signaltransmitter 7 used in the present invention usually includes a sensortransmitter 75. The body 75 also includes a circuit board 76, a battery71 electrically connected to the circuit board 76, and a firstelectrical connecting port 73 exposed to the outside.

Please refer to FIGS. 4A to 4D, which illustrate the state when thecharging device 1 is not furnished with the transmitter 7. Please referto FIG. 2 for the reference numeral of each component. In FIGS. 4A and4B, the charging module 3 is in the first operating state, the secondelectrical connecting port 30 is not actuated to be placed at the firstposition (corresponding to the bearing surface 13′ in the retractedstate) inside the opening 15, i.e., a non-charging position, the opening15 includes a sliding groove 150′, the circuit assembly 33 is disposedin the housing 10 and including a circuit board 330 and an electricalconnecting element 331. The circuit board 330 is equipped with alight-emitting element 332, and is electrically connected to the firstconductive connector 31 in the charging seat 30. The electricalconnector 331 is a flexible material that is electrically connected tothe electrical connection plug 44, usually by welding on the output endof the plug 44. The upper housing 10 a has a light-guiding element 52′disposed in the indicating area 11 at the front and a baffle exit 16 atthe rear, wherein a baffle 61 sheathed in the guiding element 10 b 1 isdisposed in the baffle exit 16. The operating portion 40 is alsodisposed in the housing 10. A push-pull key 12 is disposed at the bottomof the operating portion 40 a, and the electrical connecting plug 44 isalso locked with the fixing block 40 a on the operating portion 40. Inanother embodiment, the push-pull key can be designed as to be actuatedby the other methods.

Please refer to FIGS. 4A and 4B. A first matching portion 14 formatching with the second matching portion 70 of the transmitter 7 isdisposed in the placing portion 13 corresponding to the front of thehousing 10, rendering the transmitter 7 to be placed at a pre-determinedposition. The operating module 4 is in the first operating state,wherein the first guiding structure 41 of the operating portion 40 iscoupled to the second guiding structure 301 of the charging seat 30, andthe second guiding structure 301 is not yet sliding in the first guidingstructure 41 at this moment. In FIGS. 4C and 4D, the first guidingstructure 41 is an oblique groove with an inclined surface guiding themovement of the second guide structure 301. The operating portion 40 hasa blocked portion 43 that is locked or stopped by the stopping end 52 ofthe first locking module 5. Therefore, when the push-pull key 12 tendsto drive the operating portion 40 due to an external force or shaking ofthe operating portion 40 itself, the first guiding structure 41 will notdrive the second guiding structure 301, thereby preventing the secondelectrical connecting port 30 from being accidentally driven toward thesecond position (corresponding to the bearing surface 13′ in an extendedstate). Furthermore, because the first conductive connector 31 islighter and more compact, the potential issue of damage to the firstconductive connector 31 if a user wants to force the transmitter 7 in orout can also be avoided. FIG. 4B further discloses the position of theactuating end 51 of the first locking module 5 extending into theplacing portion 13. A pivot portion 50 pivoted on the pivot frame 10 b 2of the lower housing 10 b between the actuating end 51 and the stoppingend 52 of the first locking module (stop part) 5, so the first lockingmodule 5 has a structure similar to a rocker. When the actuating end 51is pressed down, the stopping end 52 rises (see FIG. 5A). In addition,an elastic element 53 connects the first locking module 5 with the lowerhousing 10 b, to provide elastic force to maintain the moving end 51protruding from the bearing surface 13′ when under a condition thetransmitter 7 is not placed in the charging device 1 (that is, when theactuating end 51 is not depressed).

Please refer to FIG. 4C, showing when the second guiding structure 301is not driven by the first guiding structure 41, and the sliding elementpedestal 302 does not follow the second guiding structure 301 to move,in order to avoid a moving of the charging seat 30 in an unexpecteddirection. The present invention is further provided with at least oneguiding portion 150 on the outside of the opening 15 to form a slidinggroove 150′, so that the sliding groove 150′ and the opening 15 areconnected with each other and the sliding element pedestal 302 isguiding the second electrical connecting port 30 in the sliding groove150′ to expand and contract from the opening 15 in a fixed direction.The second locking module 6 further includes a first connecting end 60.When under the first operating state, the operating portion 40 is at thefirst position, and the second connecting end 42 is connected with thefirst connecting end 60 to prevent the baffle 61 from being pushed bythe elastic element 62. At this moment, the second electrical connectingport 30 is located at a first position (contracted state relative to thebearing surface 13′), so that the second locking module 6 is presseddown to keep the baffle 61 inside the baffle exit 16, that is, notextending out of the baffle exit 16, and the second locking module 6releases the positioning of the transmitter 7 to allow the transmitter 7to be inserted in or taken out of the placing portion 13.

Please refer to FIG. 4D, which discloses another embodiment of the firstlocking module of the charging device in the present invention, whereinthe first locking module is replaced with a locking block 5, which has asliding body 50, one end of which is an actuating end 51 and the otherend is a stopping end 52, and the second guiding structure 301 of thecharging module protrudes outside the first guiding structure 41 and isblocked by the stopping end 52 on the top. When the transmitter 7 is notplaced in the placement portion 13, the locking block 5 is normallymoved toward the baffle 61 due to the spring 53 (that is, the pushingforce in the opening direction of the placing portion 13). Thus, whenthe second guiding structure 301 is pushed upward by the first guidingstructure 41, it will be blocked by the stopping end 52 and cannot moveupwardly. On the other hand, when the transmitter 7 is inserted into theplacement portion 13 in the correct direction, that is, the secondmatching portion 70 is facing inward, the transmitter 7 can push theactuating end 51 to move deeper into the placement portion 13, and thendrive the locking block 5 moves in the same direction. At this time, thestopping end 52 is moved away from the upper side of the second guidingstructure 301. Therefore, when the user drives the first guidingstructure 41 through the push-pull key 12, the second guide structure301 is driven upward, and the stop end 52 no longer blocks the secondguiding structure 301. According to the abovementioned embodiment, thefirst blocking module can restrict the movement of the second electricalconnecting port 3′ by the releasable coupling of the stopping modulewith the charging module or the operating module. The restriction of themovement that the first locking module to the second electricalconnecting port may be a complete prohibition or merely a partialdisplacement but unable to render an effective contact with the firstelectrical connecting port 73 (FIG. 3D).

Please refer to FIGS. 5A to 5C, which respectively show the state whenthe transmitter 7 is placed at the pre-determined location in thecharging device 1 and the operating portion 40 is controlled to drivethe second electrical connecting port 3′ to protrude the bearing surface13′. Please also refer to the reference numeral of each component inFIGS. 2 and 3A to 3D, which will not be repeated hereinafter. FIG. 5Ashows the state when the transmitter 7 is placed at a pre-determinedlocation of the bearing surface 13′ of the charging device 1. Even whenthe transmitter 7 is in a relatively correct position, the actuating end51 is actuated by the transmitter 7 to detect whether the transmitter 7is at a predetermined position. When the transmitter 7 is at thepredetermined position, the stop end 52 releases the locking to theoperating portion 40 to allow the operating portion 40 to drive thesecond electrical connecting port 3′ to move between the first positionand the second position, and to form a connection or separation with thefirst electrical connecting port 73. In FIG. 5A, being at thepredetermined location, the transmitter 7 presses the actuating end 51to rotate the first locking module 5, and at the same moment, thestopping end 52 is lifted and releases the blocked portion 43 so as torelease the movement restriction of the second electrical connectingport. At this moment, the elastic element 53 is compressed, and afterthe transmitter 7 is taken out, the elastic restoring force of theelastic element 53 will drive the actuating end 51 to extend upward tothe placing portion 13 (the same as the state in FIG. 4B).

Please refer to FIGS. 5B to 5C, showing the state when the operatingportion 40 is controlled to drive the second electrical connecting port3′ from the first positing moving toward the second position, after thetransmitter 7 is placed on the placing portion 13 and the push-pull key12 is operated to push out a part of the electrical connecting plug 44.In FIGS. 5B-5D, when the pushing is in the direction to the right, thestopping end 52 of the first locking module (the first locking portion)5 has been lifted and can no longer stop the blocked part 43, the secondelectrical connecting port 3′ releases the movement restriction, and thepush-pull button 12 drives the operating portion 40 to move in the samedirection. Meanwhile, the first guiding structure 41 pushes the secondguiding structure 301 to move upward, and then drives the charging seat30 to move upward from the opening 15 and toward the first electricalconnecting port 73 of the sensor 7 (in conjunction with FIGS. 3D and 6A)while having the first conductive connector 31 move toward the inserthole 731 (see FIG. 3C). At the same time, the electrical connecting plug44 partially extends out of the opening 17. In addition, when theoperating portion 40 moves to the right, the second connecting end 42 isseparated from the first connecting end 60 of the second locking portion6 (as shown in FIG. 5C), so the elasticity potential of the elasticelement 62 due to the pressing can be released to push the baffle 61 outof the baffle exit 16 and stop the rear end of the transmitter 7 toachieve the effect of positioning the transmitter 7 on the placingportion 13. Please refer to FIG. 5C, which shows the state where thetransmitter 7 is hidden to illustrate the placing portion 13 alone afterthe transmitter 7 is placed, the push-pull key 12 is operated to pushout a part of the electrical connecting plug 44, and the charging seat30 and the first conductive connector 31 thereof is at the locationduring escalating in the opening 15. Please refer to FIGS. 6A to 6D,showing the state in which the operating portion 40 is controlled todrive the second electrical connecting port 3′ at the second position,and the electrical connecting plug 44 is fully pushed out after thetransmitter 7 is inserted. Please also refer to the reference numeral ofeach component in FIGS. 2 and 3A to 3D, which will not be repeatedhereinafter. In FIGS. 6A and 6B, when the movement restriction of thefirst locking module 5 over the second electrical connecting port 30 isreleased, the operating portion 40 drives the second electricalconnecting port 3′ moves from the first position to the second position(relative to the bearing surface 13′ in an extended state) in theopening 15 and is electrically connected to the first electricalconnecting port 73, i.e. a charging position, wherein the charging seat30 extends from the opening 15 to achieve the connection with the firstelectrical connection port 73, making the first conductive connector 31enters the insert hole 731 and is electrically connected to the inputterminal 732 of the transmitter 7 (the position shown in FIG. 3C). Thepush-pull key 12 is pushed to the front of the housing 10, which is theright most portion in the drawing, and the electrical connecting plug 44also completely extends out of the opening 17. At this situation, thecircuit board 330 is also lifted to the highest position, and thelight-emitting element 332 is the closest to the light-guiding element52′. At this moment, the illumination of the light-emitting element 332can be transmitted to the indicating area 11 through the light-guidingelement 52′ and makes overall operating process have both foolproof andlight-guiding effects, and the internal space of the charging device 1is effectively used to make the charging device 1 miniaturized.

At this time, the light-emitting element 332 is ready to illuminate.When the electrical connecting plug 44 is plugged into an external powersource such as an AC power adapter, a computer USB socket, a carcharging adapter or a device equipped with a USB socket (please refer tothe charger 1 in FIG. 6H which can be plugged into a USB socket on apersonal computer 91, the charger 1 in FIG. 6I which can be plugged intoa mobile phone charger 92 or a car cigarette light USB adapter 93 inFIG. 6J), etc., so that the light-emitting element 332 can illuminateand provide indication and instructions, and indicate the usage statusof the charger 1 by different light-emitting colors and patterns.

Please refer to FIG. 6C, the operating module 3 is in the secondoperating state. It can be seen that when the push-pull key 12 is pushedto the end of front direction of the housing 10, the operating portion40 has also reached the position closest to the front end of the housing10, and at this time the second guiding structure 301 is also pushed upto the highest position by the first guiding structure 41. Relatively,the state of the electrical connecting plug 44 in FIG. 6C is pushed out,while in FIG. 4C is withdrawn back. FIG. 6C discloses that the slidingelement pedestal 302 has also lifted to a high position of the slidinggroove 150′, and the second connecting end 42 of the second lockingportion (baffle 61) 6 is separated from the first connecting end 60, sothe elasticity potential of the elastic element 62 that was originallypressed can be released to push the baffle 61 out of the baffle exit 16and stop the rear end of the transmitter 7 so as to hold the transmitter7 on the placing portion 13, positioning and locking the transmitter 7,so as to prevent the first electrical connecting port 73 and the secondconnecting port 3′ in electrical connection from accidentally pickingand placing the transmitter 7 and damaging the second connecting port 3.Furthermore, at the same moment, the second electrical connection port3′ is in a second position (relative to the bearing surface 13′ in anprotruding state), the baffle 61 extends out of the baffle outlet 61, sothat the second locking portion 6 positions the transmitter 7 on thebearing surface 13′ and prevents the transmitter 7 from being put in ortaken out from the placing portion 13 to protect the first conductiveconnector 31 of the second electrical connecting port 3′ from beingdamaged by improper operation of the transmitter 7. When the chargingmodule 3 is in the third operating state, that is, when the operatingportion 40 drives the second electrical connecting port 3′ to move fromthe second position back to the first position to separate from thefirst electrical connecting port 73, and the operating portion 40, afterthrough the second connecting end 42 pressing the first connecting end60 and lowering the baffle 61 (referring to the operating state as shownin FIG. 4C), which drives the second locking portion 6 to retract to thehearing surface 13′ to release the positioning lock of the transmitter7, so that the first connecting port 73 and the second connection port3′ is in a separated state then the sensor 7 can be taken out. Referringto FIG. 6D, which shows an embodiment that the push-pull key 12 islocated closest to the front end of the housing 10, and the positioningblock 120 can be snapped into the second positioning groove 103 b at thesame time. After the charging is completed, the first electricalconnecting plug 44 is first disconnected from the external power source,and when the push-pull key 12 is pressed into the housing 10 (pleaserefer to FIG. 1E), the positioning block 120 is separated from thesecond positioning groove 103 b, and the push-pull key 12 can be pushedtoward the first positioning groove 103 a, and finally the positioningblock 120 returns into the first positioning groove 103 a. At this time,the charging seat 30 is completely lowered, and the baffle 61 alsoreturns to the baffle exit 16 without blocking the transmitter 7, so thetransmitter 7 can be removed from the placing portion 13 at this time inorder to prevent the first electrical connection port 73 and the secondconnection port 3′ in electrical connection from damaging the secondconnection port 3′ due to accidentally taking or placing the transmitter7. Furthermore, at: this moment, the second electrical connection port3′ is at: a second position (relative to the bearing surface 13′ in anextended state), the baffle 61 extends out of the baffle outlet 61, sothat the second locking portion 6 restricts the transmitter 7 at theposition of the bearing surface 13′ and the transmitter 7 cannot be putin or taken out from the placing portion 13 to protect the firstconductive connector 31 of the second electrical connection port 3′ frombeing damaged by mis-operation to the transmitter 7. When the chargingmodule 3 is in the third operating state, that is, when the operatingportion 40 drives the second electrical connection port 3′ to move fromthe second position back to the first position to separate from thefirst electrical connection port 73, and the operating portion 40, afterthrough the second connecting end 42 pressing the first connecting end60 and lowering the baffle 61 (referring to the operating state as shownin FIG. 4C), which drives the second locking portion 6 to retract to thebearing surface 13′ to release the positioning lock of the transmitter7, so that the first connecting port 73 and the second connection port3′ is in a separated state then the sensor 7 can be taken out. See FIG.6D, it can be seen that the operation of the push-pull key 12 is inconjunction with the positioning method among the positioning block 120,the first positioning groove 103 a and the second positioning groove 103b, which can reduce friction loss of the opening 17 caused by improperoperation and improves the durability of the operating structure of theUSB connector 44. In another embodiment, the sliding design of thepush-pull key 12 does not need to press the button into the housing 10.

Please refer to FIGS. 7A and 7B both. The numerals of the devices arereferred to those in FIG. 2 and the other drawings. As shown in FIGS. 7Aand 7B, the housing 10 is removed to fully disclose the relativepositions of and the connection relationship between the controllingmodule 4 and the charging module 3. FIG. 7A shows the first operatingstate of the present invention, wherein the second guiding structure 301is located at the first position in the first guiding structure 41,where it is usually at a low position, so that the charging seat 30 ofthe second electrical connection port 3′ is maintained in a retractedposition relative to the bearing surface 13′. It can be seen from theprevious drawings and descriptions that the charging seat 30 can onlymove up and down. Therefore, in order to prevent the charging seat 30from an accidental up-and-down movement resulting from a verticalshaking, where the movement drives a movement of the controlling module4 consequently, the first guiding structure 41 of the present inventionis designed to be a guiding groove structure, and a first transversegroove 41 a extends to form at the first position, wherein the extendingdirection is perpendicular to the moving direction of the second guidingstructure 301. Therefore, when the charging module 1 is shaken in adirection parallel to the moving direction of the charging seat 30,because the extending direction of the first horizontal groove 41 a isperpendicular to the moving direction of the second guiding structure301, the movement of the charging seat 30 resulting from the shaking canbe prevented. FIG. 7B shows the second operating state according to thepresent invention, where the operating portion 40 is pushed forward, sothat the second guiding structure 301 is located at the second positionof the first guiding structure 41, usually at a high place, so that thecharging seat 30 is kept at an extended position opposite to the bearingsurface. The first guiding structure 41 of the present invention furtherextends at the second position to form a second groove 41 b, where thedirection it further extends is perpendicular to the moving direction ofthe second guiding structure 301, so as to prevent the charging seat 30from moving resulting from the shaking in a direction parallel to itsmoving direction. Please further refer to FIGS. 7A and 7B in conjunctionwith FIG. 2, where the first conductive connector 31 and the secondconductive connector 32 are inserted on the circuit board 330, and thecharging module 3 (as shown in FIG. 2) of FIG. 7B is in a state ready tocharge.

Please refer to FIG. 7C. FIG. 7C shows a vertical cross-sectional viewof the charging module and the controlling module according to anotherembodiment of the present invention. It is shown that the baffle 61 isdirectly connected to the charging seat 30 through a connecting element6′, so that the lifting and lowering of both are completelysynchronized. The charging seat 30 can also be integrally formed withthe baffle 61 and the connecting element 6′. In other words, thecharging module 3 can be integrally formed with the baffle 61 whichserves as the second locking module. The controlling module 4 and thecharging module 3 are coupled and moved interactively by a magneticforce. There is a first magnetic element MP1 disposed under the chargingmodule 3, and there are a second magnetic element MP2 and a thirdmagnetic element MP2 on the controlling module 4. The first magneticelement MP1 magnetically repulses the second magnetic element) MP2, andattracts the third magnetic element MP3. Accordingly, when thecontrolling module 4 is in the second operating state (i.e. it is pushedto the right till the end), the second magnetic element MP2 is locatedbelow the first magnetic element MP1, the charging module 3 is pushedupward through a repulsive force, and the baffle 61 is simultaneouslydriven to extend upward and to be out of the baffle exit 16.Nevertheless, when the controlling module 4 is in the first operatingstate (i.e. it is pushed to the left till the end), the third magneticelement MP3 is located under the first magnetic element MP1, thecharging module 3 is pulled downward by the attraction, and the baffle61 is simultaneously driven to retract downward and to be in the baffleexit 16.

Please refer to FIG. 8A to FIG. 9B. The numerals of the components showntherein comply with those shown in FIG. 2 and other drawings. The samecomponents as shown in the drawings and their movements are notrepeatedly described here. Please refer to FIG. 8A and FIG. 9A, both ofwhich show the top cross-sectional views of the charging module of thepresent invention with a transmitter 7 placed on the placing portion 13,and the second matching portion 70 is matched with the first matchingportion 14, so that the transmitter 7 is in a correct relative positionor a predetermined position, and the first electrical connection port 73is now aligned to the opening 15. When the charging seat 30 (referringto FIG. 6A) is lifted up, it can be correctly electrically connected tothe first electrical connection port 73. Referring to FIGS. 8A and 8B,the position of the actuating end 51 in the transverse direction isroughly equal to the position of the first matching portion 14.Therefore, only when the transmitter 7 reaches the end of the stroke,the actuating end 51 can be pressed down to make the first lockingmodule 5 rotate without stopping the blocked portion 43 (referring toFIG. 5A), and the actuation end 51 is arranged at the end of the bearingsurface 13′ to reduce the friction with the bottom of the transmitter 7.In another embodiment, the actuating end 51 is not limited to be locatedat any other position. Furthermore, because the first matching portion14 is a protruding structure that extends inward the placing portion 13(as shown in FIG. 1F), therefore, two groove areas are naturally formedon both sides of the first matching portion 14, and the actuating end 51is arranged in the groove area. Relatively, the second matching portion70 of the transmitter 7 is an inwardly formed groove structure, andtherefore two protruding structures are formed on both sides of thesecond matching portion 70. Accordingly, when the second matchingportion 70 is matched with the first matching portion 14, the twoprotruding structures on both sides of the second matching portion 70will go into the respective groove areas, and thereby the protrudingstructures will trigger the actuating end 51 so that the stopping end 52is tilted up and no longer blocks the blocked portion 43. At thismoment, the baffle 61 can extend from the baffle exit 16 to block thebottom surface of the tail end of the transmitter 7 to achieve theeffect of locking transmitter 7. In FIG. 8B, when the transmitter isinserted into the charger 1 in an incorrect direction, e.g. when thetail end of the transmitter 7 goes into the placing portion 13, becauseit is blocked by the first matching portion 14, the front end of thetransmitter 7 is pressed down above the baffle 61 so that the baffle 61cannot extend from the baffle exit 16, and the first electricalconnection port 73 is not aligned with the opening 15. Meanwhile,because the tail end of the transmitter 7 cannot reach the end of theinsertion stroke so that the transmitter 7 cannot press down theactuating end 51, the stopping end 52 keeps on blocking the blockedportion 43. Therefore, the operating portion 40 cannot move, and thecharging seat 30 cannot be exposed from the top surface of the opening15, which prevents the first conductive connector 31 from abnormallycolliding with the transmitter 7 and any possible damage, and thereby toprolong the lifetime of the charging device 1. That is to say, a safestate that prevents the first conductive connector 31 on the secondelectrical connection port 3′ from colliding with the transmitter 7 canbe maintained. At this moment, the second connecting end 42 stillrestricts the first connecting end 60 so that the baffle 61 cannotextend. When this phenomenon occurs, it can also serve as a reminder tothe user that the transmitter 7 is placed in a wrong direction.

Please refer to FIGS. 9A and 9B. In comparison with FIGS. 8A and 8B, theactuating end 51 is arranged away from the groove area. During theplacing procedure of the transmitter 7, the two protruding structuresfirstly press down the actuating end 51 so that the stopping end 52 islifted up and no longer blocks the blocked portion 43, then the twoprotruding structures 2 go into the groove areas to be engaged with thefirst matching portion 14, and the baffle 61 can extend from the baffleexit 16 to block the tail end of the transmitter 7. In FIG. 9B, when thetransmitter is inserted into the charger 1 in the incorrect direction,because the tail end of the transmitter 7 goes into the placing portion13, the bottom of the front end of the transmitter 7 is pressed downabove the baffle 61 so that the baffle 61 cannot extend from the baffleexit 16, and the first electrical connection port 73 is not aligned withthe opening 15. Meanwhile, although the transmitter 7 can trigger theactuating end 51 and cause the stopping end 52 to tilt up and no longerblock the blocked portion 43, however, the movable distance of theoperating portion 40 is controlled so that at least the first conductiveconnector 31 cannot be exposed from the top surface of the opening 15,which thereby prevents the bottom of the transmitter 7 and the firstconductive connector 31 from being damaged due to abnormal operation. Atthis moment, only a portion of the plug 44 can be pushed outwards. Itcan still serve as a reminder of an occurrence of a mistake to the userthat the transmitter 7 is placed in an incorrect direction. That is tosay, a safe state that prevents the first conductive connector 31 on thesecond electrical connection port 3′ from colliding with the transmitter7 can be maintained.

Please further refer to FIG. 10. FIG. 10 shows a schematic drawing ofthe contact of the first conductive connector of the present invention.The first conductive connector 31 is presented as, but not limited to, agolden finger-shaped contact, and the contact terminal 310 of the firstconductive connector 31 has a similar configuration as that of theoutput terminal 812 of the sensor (as shown in FIGS. 3B-3D). Therefore,both the contact terminal 310 and the output terminal 812 are adapted tobe inserted into the insert hole 731 of the first electrical connectionport 73 of the transmitter 7, so that the first conductive connector 31can share the first electrical connecting port 73 with the outputterminal 812 to save the internal space of the transmitter 7. Pleasefurther refer to FIG. 10 as well as FIG. 11. FIG. 11 shows a schematiccircuit diagram of the charging device and the transmitter of thepresent invention, which discloses that the circuit assembly 33 in thecharger 1 has a charging circuit group 1A and a calibrating circuitgroup 1B. The contact terminal 310 of the first conductive connector 31is presented as, but is not limited to, 8 contacts: BAT, SW, RX, TX, E1,E2, E3 and E4, which number can be adjusted according to the number ofcontacts of the sensor output terminal 812. The charging circuit group1A is electrically connected to the third electrical connection port 44to input power. The charging circuit group 1A is used to provide andcontrol a charging voltage, and the charging circuit group 1A thencharges the transmitter 7 through the contact BAT, with the contact SWserving as a charging switch, by outputting the charging voltage to thetransmitter 7. The remaining contacts are used to connect thecalibration circuit group 1B of the charging device 1 and thetransmitting module 74 of the transmitter 7 to facilitate the detectionto the transmitter functions including data transmission, control anddetection of self-calibration, leakage current measurement and/orresistance measurement. In another embodiment, the charging device 1 mayonly provide a charging function.

Please refer to FIGS. 12A to 12F. FIG. 12A shows a moisture-proofassembly 2 having a housing 20 generally in the form of a can body, atleast such as one of a cylindrical, elliptical cylindrical or oblatecylindrical cans, for accommodating the charging device 1 or thetransmitter 7 or the charging device 1 containing the transmitter 7 toform a moisture-proof assembly 2. The moisture proof assembly 2 has anopening 23′ and a first buckling edge 23 formed next to the opening 23′.The opening 23′ has an opening direction perpendicular to the opening23′, and the protruding direction of the first buckling edge 23 isperpendicular to the opening direction. A cover 24 is movably arrangedon the housing 20 and used to seal the opening 23′. A second bucklingedge 25 is also formed inside the cover 24, and its protruding directionis opposite to that of the first buckling edge 23 to buckle the firstbuckling edge 25 and the second buckling edge 25 mutually. Furthermore,the housing 20 has an elastic element 22. When the charging device 1 isplaced in the housing 20 and the cover 24 seals the opening 23′, thecharging device 1 is pressed down by the cover 24 and retracted into thehousing 20, thereby the elastic element 22 is elastically deformed(please referring to FIG. 12C). When the cover 24 is opened, the elasticelement 22 releases its elastic potential to push the charging device 1outwards, so that at least a part of the charging device 1 is protrudedfrom the housing for a user to take the charging device 1 out (as shownin FIG. 12B). When the transmitter 7 needs to be charged, the chargingdevice 1 is taken out of the housing 20, so that an external powersource can be used to connect and charge the transmitter 7. The elasticelement 22 can be a compression spring, such as a conical spring, a coilspring, a spiral spring, etc., so that the elastic element 22 interfereswith the charging device 1, and thus can also fix the position of theaccessory (e.g. the charging device 1 or the transmitter 7) placed inthe housing 2 to prevent from shaking. As shown in FIG. 12C, a conicalspring is used. Because the diameters of the coils from the top to thebottom of the conical spring are significantly increased, when the cover24 seals the opening 23′ as shown in FIG. 12C, the charging device 1 ispressed down into the housing 20, and the charging device 1 furthercompresses the elastic element 22, the upper coils can be pressed downinside the lower coils. Accordingly, this kind of spring can becompressed to a shorter length than the cylindrical coil spring, and hasthe advantage of a reduced volume of the moisture-proof assembly. Whenthe charging device is in the inserted state, the spring compressionheight H_(compress) plus the length H1 of the charging device is lessthan the housing height H2. When the charging device is not in theinserted state, the spring extension height H_(extend) plus the lengthH1 of the charging device is larger than the housing height H2. Pleasecontinue to refer to FIGS. 12A and 12C, wherein the housing 20 isfurther divided into a first accommodating space 20′ and a secondaccommodating space 21. The first accommodating space 20′ is used tostore the charging device 1, the second accommodating space 21 is usedto contain the desiccant 29, and there is a hole structure 28 betweenthem, so that the moisture in the first accommodating space 20′ can passthrough the hole structure 28 to the second accommodating space 21, andthe moisture can be absorbed by the desiccant 29, to prevent thetransmitter 7 from getting wet. The transmitter 7 disclosed according tothe first embodiment is approximately 32.8 mm*19.8 mm*4.15 mm (+/−0.5mm), the size of the charging device 1 is approximately 40*26*23 mm(+/−0.5 mm), and the transmitter is installed on the charging device.The volume of the moisture-proof assembly 2 is no more than 200 cubiccentimeters, or between 12 and 138 cubic centimeters, or between 30 and70 cubic centimeters, or multiply the length by the width to controlfrom 3 to 28 centimeters. The diameter range of the moisture-proofassembly 2 is designed to be 2 to 5 cm, and its height is designed to be4 to 7 cm, so that the volume of the moisture-proof component isminiaturized and convenient for users to carry.

Please referring to FIGS. 12D to 12F, which disclose that thetransmitter 7 is placed in the moisture-proof assembly 2 according otherembodiments of the present disclosure. FIG. 12D discloses a state inwhich only the transmitter 7 is placed in the moisture-proof assembly 2having the hole structure 28. The desiccant 29 is also disposed in thehousing 20, such as the bottom. In FIG. 12E, it is revealed that theelastic element 22 is directly disposed on the bottom of the housing 20,and the desiccant 29 is also disposed in the housing 20. In addition,the desiccant 29 can also be selectively disposed on the inner surfaceof the cover 24. When the housing 20 is opened, the desiccant 29 willface outwards for easy replacement. As for FIG. 12F, it reveals thestate where only the transmitter 7 is placed in the moisture-proofassembly 2 having the hole structure 28. In another embodiment, thedesiccant 29 may be integrally formed in the housing or the inner wall,so that the housing 20 does not need to distinguish differentaccommodation spaces (not shown in the figure). In addition, the pushedportion 27 facilitates the user to open the cover 24. The moisture-proofassembly 2 can be used to properly protect the charging device 1 when itis not in use and isolate it from outside moisture, and further use theinternal desiccant to dehumidify the transmitter 7 and/or the chargingdevice 1 to extend the service life, which can prevent moisture fromdamaging electronic parts. The housing 20 can also be provided with astructure similar to the observation area 21′. The observation area is apart of the housing 20, and is made by injection molded from transparentor translucent materials. If a desiccant that can absorbs moisture tochange color or an additional desiccant indicator is used, it is easy tocheck the moisture status of the transmitter 7 and/or the chargingdevice 1.

The method of using the moisture-proof assembly 2 is to provide the userwith a first transmitter and a second transmitter at the same time,wherein the first moisture-proof assembly includes a first transmitterand a moisture-proof assembly 2, the second moisture-proof assemblyincludes a second transmitter combined with a charging device, and thesecond moisture-proof assembly is disposed in the moisture-proofassembly 2. The user will firstly use the first transmitter formeasurement. When the power of the first transmitter is low enough to alower limit, it is removed from the sensor pedestal, and the secondtransmitter and the charging device 1 are taken out from themoisture-proof assembly 2. The second transmitter is used to install tothe sensor pedestal, and the first transmitter is put into the placingportion 13 of the charging device 2 to be charged. After said chargingis completed, the first transmitter and the charging device areassembled to return to the moisture-proof assembly 2 for storage, sothat the first transmitter and the second transmitter can be charged andused alternately. The moisture-proof assembly 2 used for the firsttransmitter is in any form of container.

Please refer to FIG. 13A, which is another embodiment of the chargingdevice of the present invention, and please also refer to FIG. 2. Thedifference from the previous embodiments is that the charging device 1electrically connects the third electrical connecting port (USB socket44′) and the circuit board 330 of the second connecting port 3′ to eachother through a wire 331′. The wire 331′ also has a certain flexibilityto adapt to the lifting of the charging module 3 for bending. Inaddition, FIG. 13A differs from the previous embodiment in that: thethird electrical connecting port uses a USB socket 44′ instead of theelectrical connecting plug 44 (USB plug), and it also forms a powerstorage unit 45 by combining a rechargeable battery 46 and a powercircuit board 47. The power storage unit 45 is electrically connected tothe charging module 3 to input power to charge the transmitter 7. Inaddition, the user can also connect the USB socket 44′ to an externalpower source to recharge the rechargeable battery 46 to increase theease of use. In another embodiment, the power storage unit 45 can omitthe USB socket and be equipped with disposable batteries, such as drybatteries and button batteries commonly available in the market. Inanother embodiment, the rechargeable battery 46 can also be omitted, andthe USB socket 44′ is connected to an external power source 9 (FIG. 13B,and symbols 91, 92, 93 in FIG. 6E) to supply power for charging thetransmitter 7. As for the operating portion 40 of the operating module 4shown in FIG. 2, although it is not disclosed in FIG. 13A, it is stillused in this embodiment. However, it is not shown in this figure becauseit is covered by the power storage unit 45, and the connectionrelationship and driven linkage between the operating portion 40 and thesecond electrical connecting port 3′ of the charging module 3 are mainlythrough the coupling between the first guiding structure 41 and thesecond guiding structure 301, and the action relationship between thetwo is the same as before. However, the difference from the previousembodiment is that the operating portion 40 in FIGS. 13A and 13B is notfixed to the USB socket 44′ (third electrical connecting port). On thecontrary, the USB socket 44′ is only fixed in the charging device 1. Thejack of the socket 44′ is exposed, therefore when the push-pull key 12is operated, only the second guiding structure 301 is driven by thefirst guiding structure 41, and the USB socket 44′ does not move. Pleaserefer to the previous drawings and descriptions for the efficacies ofother components in FIG. 13A, and will not be repeated here.

Please refer to FIG. 13B, which is another embodiment of the chargingdevice of the present invention. Please also refer to FIG. 2. Thebiggest difference between the embodiment in FIGS. 13B and 13A is thatthe power storage unit 45 is electrically connected to the power circuitboard 47 to the circuit board 330 for the charging seat 30 through acoiled wire 331″. Basically, the displacement of the charging device 1with the push-pull button 12 (not shown in FIG. 13B) drives the liftingof the charging seat 30 and the circuit board 330 of the secondelectrical connecting port 3′, thereby indirectly drives the expansionand contraction of the coiled wire 331. In another embodiment, thecoiled wire 331″ can also be replaced by a spring connector (POGO pin).As for the efficacies of other components, please refer to the previousdrawings and descriptions, it is not repeated here. In FIGS. 13A and13B, the USB socket 44′ being as the third electrical connecting port isdesigned without moving back and forth.

Please refer to FIGS. 14A and 14B, another embodiment of the chargingdevice is disclosed. The charging device 1 includes a placing portion 13for placing the transmitter 7, the placing portion 13 also includes abearing surface 13′ for placing the transmitter 7, and the bearingsurface 13′ includes an opening 15 (FIG. 4A). A charging module 3 isprovided on the opposite side of the bearing surface 13′, and includes asecond electrical connecting port 3′, a circuit assembly 33, and a thirdelectrical connecting port 44. The second electrical connecting port 3′is arranged at an opening 15 (see FIG. 4A) for electrical connectingwith the first electrical connecting port 73 (see FIG. 3D), and thethird electrical connecting port 44 is used for connecting an externalor internal power source (see the symbols 91, 92, 93 in FIG. 6E or thesymbol 46 in FIG. 13B). The circuit assembly 33 (please refer to FIG. 2)is connected between the second electrical connecting port 3′ and thethird electrical connecting port 44 to perform charging and chargingcontrol for the physiological signal transmitter 7. The opposite side ofthe bearing surface 13′ is also provided with a control module tocontrol the safe operation between the transmitter 7 and the chargingmodule 3. The control module includes an operating portion 40 fordriving the second electrical connecting port 3′ to connect to the firstelectrical connecting port 73. A first locking module 5 is also providedon the opposite side of the bearing surface 13′, can releasably restrictthe electrical connection between the second electrical connecting port3′ and the first electrical connecting port 73, or is used to furtherrestrict the displacement of the second electrical connecting port 3′.For the detailed operation of the first locking module 5, please referto FIGS. 4B, 5A, and 6B, which will not be repeated here. Please referto FIGS. 14A and 14B, the bearing surface 13′ is provided with a secondlocking module 61 at the other end relative to the indicating area 11,and the second locking module 61 can be extended and contracted on thebearing surface 13′ to fix the position of the transmitter 7. Further,the second locking module 6 includes a baffle 61, which is sleeved on aguide rod 10 b 3 to be able to move up and down, connected to the bottomof the bearing surface 13′ by a spring 62′, and the elasticity providedby a spring 62 keeps the baffle 61 normally protruding from the bearingsurface 13′. Please also refer to FIGS. 14A to 14B. When the transmitter7 is deposited on the bearing surface 13′, the transmitter 7 will firstpress and retract the baffle 61 into the bearing surface 13′ during thedepositing process. After the first and second matching portions 14, 70are matched, the transmitter 7 just leaves the top of the baffle 61without blocking it. At this time, the baffle 61 is forced by theelastic restoring force of the spring 62′ and protrudes on the bearingsurface 13′ again. When the transmitter 7 is to be taken out, thepush-pull button 12 is firstly pushed to the left to lower the chargingseat 30 to release the electrical connection, and then the baffle 61 ispressed below the bearing surface 13′, so that it no longer blocks thetransmitter 7 at the tail portion, and the transmitter 7 can betranslated to the left away from the bearing surface 13′. The featuresof the second locking module 6 shown in FIGS. 14A and 14B can also beapplied to other embodiments of the charging device of the presentinvention. As shown in FIG. 1A, the baffle 61 retracted below thebearing surface 13′ can be regarded as being pressed by the user tofacilitate the insertion of the transmitter 7 into the placing portion13. The user can also directly press the baffle 61 through thetransmitter 7 as shown in FIG. 14A. During the depositing process, ifthe second matching portion 70 is correctly inserted into the placingportion 13 inward so that it fits with the first matching portion 11 toachieve the result that the transmitter 7 is in the correct relativeposition, the baffle 61 will be no longer blocked by the transmitter 7but can be pushed by the restoring force of the elastic element 62(FIGS. 2 and 5B) to protrude from the bearing surface 13′ again becausethe transmitter 7 has reached the correct position that is not so deep.It can be seen that if the baffle 61 shown in FIGS. 14A and 14B is used,the first engagement end 60 of the second locking module 6 and thesecond engagement end 42 of the operating portion 40 can be eliminatedand not provided.

Please refer to FIG. 15, which discloses an embodiment without a coverplate 10 a 1. Therefore, the bearing surface 13′ itself serves as aplacing portion, and an indicator area 11 is provided at one end of thebearing surface 13′ as a first fitting portion that can provide a visualcue effect so that the user can connect, fit, and join the secondmatching portion 70 with the placing portion. The actuating end 51(FIGS. 1D, 1F, 2, and 4B) of the first locking module 5 (FIGS. 2 and 4B)also protrudes on the bearing surface 13′. In addition, a baffle exit 16is provided at the other end of the bearing surface 13′, in which thebaffle 61 (FIGS. 2, 4C and 5C) is located. Since there is no cover plate10 a 1 in this embodiment, in order to prevent the transmitter 7 fromdetaching upward (that is, the axial direction of the bearing surface13′), the bearing surface 13′ is further provided with the second bucklestructure 83 on the pedestal 80 as shown in FIG. 3D. The second bucklestructure 83 is used to generate a buckling effect with the first bucklestructure 72 of the transmitter 7, and enables the transmitter 7 to befixed on the bearing surface 13′. In addition, in order to make thetransmitter 7 more stable on the bearing surface 13′ without falling offdue to accidental impact, side walls 102′ are formed on the bearingsurface 13′, which are usually arranged in pairs. That is, on both sidesof the bearing surface 13′, when the transmitter 7 is fixed on thebearing surface 13′, the side walls 102′ are attached to the two sidesof the transmitter 7, so as to assist in fixing the transmitter 7 in thelateral direction. As for the efficacies of other components, pleaserefer to the previous drawings and descriptions, which will not berepeated here.

Please refer to FIGS. 16A to 16B, which are another embodiment of thecharging device. Except the components and structures for the pressingbutton 12′, the stopping end 52 of the first locking module 5 and theavoidance notch 52′ are different from the previous figures, the rest ofthe components and structures are the same as those of the previousfigures. The second connecting port 3′(or the charging seat 30) is in away of moving up and down, and therefore the second connecting port 3′of this embodiment is connected to the pressing key 12′ to drive thelifting or descending of the charging seat 30, which is usually a latchbutton structure, and the pressing member 12′ can also be used as a partof the charging module 1, or can be a component that is operatedindependently. When the pressing key 12′ is pressed once, the chargingseat 30 will rise and stay stuck. When the pressing key 12′ is pressedagain, it will release the lock and return to the original position,i.e., the position when the pressing key 12′ is not pressed. When thepressing key 12′ is pressed, the second sliding element 302 of thecharging seat 30 also slides up and down between the two guidingportions 150. Alternatively, the pressing key 12′ can be positioned bythe positioning button 180, which will be described in detail later.Please refer to FIG. 16A, which discloses that the transmitter 7 has notbeen inserted into the placing portion 13, so the actuating end 51 ofthe stopping module 5 also extends into the placing portion 13 (pleaserefer to FIG. 1D) at this time. At this time, if the pressing key 12′ ispressed into the body, the stopping end 52 will have a blocking effecton the blocked portion 43, thereby blocking the charging seat 30 fromentering the placing portion 13. In another embodiment, the blockedportion 43 may also be formed on the charging seat 30 (not shown), orthe locking slider 5 may be used in another embodiment as shown in FIG.4D. Please refer to FIG. 16B, it discloses that the transmitter 7 hasbeen inserted into the placing portion 13, so the actuating end 51 hasbeen pressed down by the transmitter 7 at this time, and the firstlocking module 5 is rotated so that the avoidance notch 52′ is alignedwith the blocked portion 43. In other words, causing the stopping end 52to move away from the upper part of the receiving part 43. At this time,if the pressing key 12′ is pressed into the body, the blocked portion 43can continue to rise by avoiding the notch 52′, so that the chargingseat 30 enters the placing part 13. When the pressing key 12′ movesinward, the stopping end 52 enters the avoidance space 43′correspondingly to avoid interference with the pressing key 12′. Inaddition, as shown in FIGS. 16C and 16D, the pivotal frame 10 a 2 of theupper housing 10 a and the pivotal frame 10 b 2 of the lower housing 10b clamp the pivotal portion 50 of the first locking module 5 in arotatable manner. The lower housing 10 b also has a push-resistingstructure 10 b 3 to prevent the movement of the stopping end 52 so as toprevent the actuating end 51 from overextending into the placing portion13. The charging device 1 further includes a second locking module 6,which is provided with a positioning portion 61 connected to an elasticunit 62 (as shown in FIGS. 5C, 6A), so that the positioning portion 61can be extended out of the bearing surface 13′ upwardly and downwardlyto lock an installation position of the physiological signal transmitter7.

Please refer to FIG. 16E, in order to fully observe the relationshipbetween the positioning button 180 and the positioning groove 10 b 3,the positioning button 180 has been moved from the positioning groove 10b 3 to the upper side. The positioning groove 10 b 3 has a firstpositioning block 10 b 31 and a second positioning block 10 b 32arranged in pairs. Below the first positioning block 10 b 31 is thefirst state position 10 b 31 p, i.e., the position when the pressing key12′ is at the lowest bottom. The positioning shoulder 180 a can beblocked by the first positioning block 10 b 31, thereby preventing thepositioning button 180 from moving upwards, i.e., blocking the pressingkey 12′ from moving upward. Above the second positioning block 10 b 32is the second state position 10 b 32 p, i.e., the position when the key12′ is at the top. The positioning shoulder 180 a can be blocked by thesecond positioning block 10 b 32, thereby preventing the positioningbutton 180 from moving downward, i.e., blocking the pressing key 12′from moving downward. Furthermore, to move the pressing key 12′ in thefirst state position 10 b 31 p to the second state position 10 b 32 p,it is only necessary to press the positioning button 180 inward to bendthe elastic structure 180 c and align the channel 180 b to the firstpositioning block 10 b 31 and the second positioning block 10 b 32,i.e., operating the pressing key 12′ or pushing the positioning button180 upward. At this time, the positioning blocks (10 b 31, 10 b 32) passthrough the passage 180 b correspondingly without being blocked by thepositioning shoulder 180 a. In the same way, if you want to return thepressing key 12′ to the lowest position, i.e., the position in the firststate, then press the positioning button 180 inward to bend the elasticstructure 180 c, and align the channel 180 b with the second positioningblock 10 b 32 and the first positioning block, i.e., the positioningbutton 180 can be pushed down to drive the pressing key 12′ back to theposition of the first state. In addition, a reset element (not shown inthe figure, it can be an elastic element or a magnetic element) can alsobe provided between the pressing button 12′ or the second electricalconnection port 3′ and the upper housing 10 a or the lower housing 10 b,i.e., when the pressing key 12′ is pressed so that the second electricalconnecting port 3′ is electrically connected to the first electricalconnecting port 73, giving the reset element a bit of energy. Thepressing key 12′ relies on the positioning shoulder 180 a to abut thesecond positioning block 10 b 32 to resist this position energy.Furthermore, when the positioning button 180 is pressed inward and thechannel 180 b is aligned with the second positioning block 10 b 32, thepositioning shoulder 180 a is no longer blocked by the secondpositioning block 10 b 32, and the position energy can be released.Thus, the pressing key 12′ returns to the initial position.

Those skilled in the art can understand from the aforementioned FIG. 2and various embodiments of the present invention that the chargingmodule disclosed in the charging device 1 can independently cooperatewith the transmitter 7, the charging modules can be used by combiningwith the operating module (such as the operating portion of FIG. 4A),the first locking module (such as the first locking portion 5 or thelocking slider 5 in FIGS. 4B, 4D), or the second locking portion (suchas the baffle 61 of FIG. 4C or 14A, which is driven by the secondelectrical connecting port 3′ through the connecting 61′ element (FIG.7C)). Alternatively, the charging module 3 is used in conjunction withthe operating module 4 and the first locking module 5 at the same time(such as the operating portion 40 and the first locking part 5 in FIG.4B); or the charging module 3 is used with the operating module 4 andthe second locking portion 6 at the same time (the operating portion 40and the second locking portion 6 in FIG. 4C), or the charging module 3is used in conjunction with the operating module 4, the first lockingmodule 5, and the second locking portion 6 at the same time.
